Motor power entries cover AC-3e (enhanced) and standard AC-3 duty across voltages from 230 V to 1000 V. At 400 V AC-3e it delivers 315 kW; at 690 V it reaches 500 kW. AC-4 duty (plugging, inching) also backed at similar levels – 450 kW at 690 V AC-4. For resistive heating (AC-1) the thermal current Ith is 1050 A, with power dissipation per pole of 70 W. That allows you to do panel heat calculations: three poles at 70 W each, plus coil losses. Making capacity is 7220 A at 440 V; breaking capacity is 5550 A at 440 V. These numbers drive coordination with upstream breakers or fuses. Associated fuse ratings are given: 630 A aM, 500 A aM, 1250 A gG at 1000 V, and UL Type L at ≤600 V – match to your system voltage and short-circuit capability. Maximum operating rate: 600 cyc/h for AC-3 and AC-3e, 300 for AC-1, 150 for AC-4.
